SPECIFICATION forming part of Letters Patent No. 656,228, dated August21, 1900.

Application filed November 6, 1899. Serial No. 735,898. (No model.)

To all whom, it may concern:

Be it known that we, JOSEPH J. TYNAN and HENRY O. MOSTILLER, citizens ofthe United States, residing in the city and county of Philadelphia, inthe State of Pennsylvania, have invented certain new and usefulImprovements in Devices for Supporting Riveting and other Apparatus, ofwhich the following is a specification.

In the insertion of rivets of large size in the hulls of vessels,bridges, tanks, and similar structures, where a great number of largerivets are employed, distributed over an extensive surface area, it isdesirable that the heavy riveting machine employed to upset the heads ofthe rivets should be mounted upon carrying mechanism which will supportit and enable it to be moved as expeditiously and easily as possiblefrom point to point to operate upon the successive rivets, and such acarrying mechanism it is the object of our invention to provide.

The large rivets applied to structures of the character referred to areusually inserted into the previously punched rivet holes from the upperor inner sides, so that the free ends of the rivets project outside andbelow. Consequently the riveting machine which upsets the projectingends of the rivets must frequently be supported on the under sideof thevessel or structure, and the plunger or hammer be driven upwardlyagainst the depending free ends of the rivets. The apparatus invented byus and shown in the drawings is illustrated as supported by and below astructure upon the rivets of which it is supposed to operate.

In the accompanying drawings we show, and herein we describe, a goodform of a convenient embodiment ofour invention, the particularsubject-matter claimed as novel being hereinafter definitely specified.

In the drawings,

Figure 1 is a view in side elevation of an apparatus convenientlyembodying our invention.

Figure 2 is an under plan view of the same.

Figure 3 is a vertical, longitudinal, sectional, elevation through theupper portion of the traveling hanger.

t Figure 4 is a view in end elevation of the traveling hanger, thesupporting rail being shown in section and the balls of the ball bearingbeing illustrated in dotted lines.

Similar letters of reference indicate corresponding parts.

In the accompanying drawings,

A indicates the skin or hull of a vessel, or any permanentpart of astructure upon the rivets of which the riveting machine may operate.

B B are a pair of supporting brackets of any preferred character,theupper portions of which happen to project through the wall or structureA, and to'be secured in position therein by nuts I) applied thereto,while the lower ends of said brackets respectively encircle or clasp therespective extremities of a supporting rail C.

The brackets B maybe each conveniently formed in two parts pivotallyconnected intermediate of their length, with the result that thesupporting rail is,with the lower por tions of the brackets,'capabl'e ofslight lateral swinging motion with respect to the upper portions.

The supporting rail C is preferably of circular section, and may beconveniently formed of a length of metal pipe.

D is a carrying arm which may in practice he made of any desired length,as, for instance, fifteen or twenty feet, and which is at a point in thevicinity of its center pivotally, i. e. hingedly, connected with, so asto have movement of rotation with respect to, a traveling hanger Emounted upon and free for longitudinal movement with respect to thesupporting rail. The carrying arm may,similarly to the supporting rail,be formed from a length of metal pip The upper portion of the travelinghanger E consists of asleeve F which in the embodiment of our inventionillustrated, encircles the supporting rail, the bore of which sleeve isof diameter slightly in excess of the external diameter of thesupporting rail, and is provided with a series of balls through whichthe sleeve rests and bears upon said rail.

Conveniently two or more circumferential series of balls 6 e areemployed at each end of the sleeve, mounted in ball races formed in therespective ends of the sleeve, as shown particularly in Figure 3.

Conveniently the ball races are constituted by and between shoulders atthe inner ends of enlargements or countersinks formed at the respectiveextremeties of the bore,-and the inner ends af annular nuts 9 mountedinthreaded engagementin said enlargements or countersinks.

The opposing faces of the shoulders on the one hand, and the inner endsof the annular nuts g on the other, are oppositely inclined as shown inFigure 3, with the result that the ball races formed have overhanginglips which serve to maintain the balls in position when the sleeve isnot in place upon the supporting rail.

The ball races are preferably provided each with a basal bearing face ofsteel, conveniently formed as a steel ringf of suitable dimensions,inserted in position in the enlargements or countersinks.

The two series of balls in each ball race are separated from each otherby an annular dividing plate f formed of hardened steel.

The sleeve as stated rests upon the rail through the interposedballs,and, manifestly, in its travel along said rail, rolls upon saidballs, with the result that its movement requires the minimum ofexertion.

Similarly, as will be understood, the hanger is capable of a swingingmovement in a plane perpendicular to the axis of the supporting rail.

The lower end of the hanger constitutes a shank h which in theparticular embodiment illustrated, is pivotally or hingedly connected tothe carrying arm by projecting through a vertical opening formed in thecentral portion of said arm, beneath which arm said shank is providedwith a series of nuts and washers z threaded upon it which serve to holdthe arm up against the shoulder at the upper end of the shank.

The outer end of the arm is provided with a swinging yoke J ofwell-known character, in which the riveting or other machine K isemployed is carried.

The inner end of the arm is provided with a strut L the free end ofwhich is provided with a wheel ball or caster M in contact with theadjacent surface of the structure A.

The carrying arm supporting the riveting machine is by reason of beingsupported at a point near its center, and by virtue of the contact ofthe strut with the structure A, normally maintained in a position insubstantial parallelism with the surface operated upon.

The contact of the strut with the surface A, in the operation of theriveting machine, tends to counterbalance the downward thrust or recoilso to speak, incident to the impact of the air or steam driven rivetinghammer against a rivet.

As willbe understood, the riveting machine K 1nay,by reason of thecarrying arm being pivotally supported by the hanger as described, andof the hanger being capable of movement from end to end of thesupporting rail, be shifted to any selected point within a large area ofthe surface A, and may operate, of course, upon all the rivets insuccession within said area without further adjustment of the parts orother movements save the pivotal movement of the arm upon thehanger andthe traveling movement of the hanger upon the rail.

It is only after all the rivets within the large area referred to havebeen operated upon that it is necessary to remove the brackets B fromthe structure A and carry the entire apparatus bodily to a differentarea of operation.

As will be understood, the operator in charge of the riveting machine,moves it to any desired point Within the range of operation of thesupporting mechanism, without leaving his position by the machine, as heeffects both the swinging movement of the carrying arm, and thelongitudinal movement of the arm and hangeriogether along the supportingrail, by the application of slight manual force to the yoke or outer endof the arm.

The strut L requires no attention; it simply follows the movement of thecarrying arm.

Having thus described our invention, we claim- 1. In an apparatus formovably supporting a riveting or other apparatus, in combination, asupporting rail, means for supporting said rail, a traveling hangerformed or pro vided with a sleeve which encircles said rail and isadapted to have both longitudinal and circumferential movement withrespect to it, anti-friction devices disposed between said sleeve andsaid rail, and a carrying arm secured to said hanger by a swivelconnection so as to be capable of revolving movement on an axisperpendicular to the axis of the rail, substantially as set forth.
